Introduction to Microsoft Excel
By-- SATISH KUMAR BARANWAL
What
is Microsoft Excel?
Microsoft Excel is a spreadsheet
program that is used to record and analyse numerical data. Think of a
spreadsheet as a collection of columns and rows that form a table. Alphabetical
letters are usually assigned to columns and numbers are usually assigned to
rows. The point where a column and a row meet is called a cell. The address of
a cell is given by the letter representing the column and the number
representing a row.
How
to Open Microsoft Excel?
Running Excel is not different from
running any other Windows program. If you are running Windows with a GUI like
(Windows XP, Vista, and 7) follow the following steps.
- Click on start
menu
- Point to all
programs
- Point to
Microsoft Excel
- Click on Microsoft
Excel
Alternatively, you can also open it
from the start menu if it has been added there. You can also open it from the
desktop shortcut if you have created one.
For this tutorial, we will be working
with Windows 8.1 and Microsoft Excel 2013. Follow the following steps to run
Excel on Windows 8.1
- Click on start
menu
- Search for Excel
even before you even typing, all programs starting with what you have
typed will be listed.
- Click on

Understanding
the worksheet (Rows and Columns, Sheets, Workbooks)
Three
most important components of Excel is which you need to understand first:
#1.
Workbook
A
workbook is a separate file just like every other application has. Each
workbook contains one or more worksheets. You can also say that a workbook is a
collection of multiple worksheets or can be a single worksheet. You can add or
delete worksheets, hide them within the workbook without deleting them, and
change the order of your worksheets within the workbook.
#2. Worksheet
A
worksheet is made up of individual cells which can contain a value, a formula,
or text. It also has an invisible draw layer, which holds charts, images, and
diagrams. Each worksheet in a workbook is accessible by clicking the tab at the
bottom of the workbook window. In addition, a workbook can store chart sheets;
a chart sheet displays a single chart and is accessible by clicking a tab.
#3. Cell
A
cell is a smallest but most powerful part of a spreadsheet. You can enter your
data into a cell either by typing or by copy-paste. Data can be a text, a
number, or a date. You can also customize it by changing its size, font color,
background color, borders, etc. Every cell is identified by its cell address,
cell address contains its column number and row number (If a cell is on 11th row
and on column AB, then its address will be AB11).
Window
Components
Before you start using it, it’s really
important to understand that what’s where in its window.
#1. Active Cell
A cell which is currently selected. It will be
highlighted by a rectangular box and its address will be shown in the address
bar.
You can activate a cell by clicking on it or by using
your arrow buttons. To edit a cell, you double-click on it or use F2 to as
well.
#2. Column
A column is a vertical set of cells. A single worksheet
contains 16384 total columns.
Every column has its own alphabet for identity, from A to
XFD. You can select a column clicking on its header.
#3. Row
A row is a horizontal set of cells. A single worksheet
contains 1048576 total rows. Every row has its own number for identity,
starting from 1 to 1048576.
You can select a row clicking on the row number marked on
the left side of the window.
#4.
Fill Handle
It’s a small dot present on the lower right corner of the
active cell. It helps you to fill numeric values, text series, insert ranges,
insert serial numbers, etc.
#5.
Address Bar
The address bar is the small input bar at the left side
of the window.
It shows the address of the active cell. If you have
selected more than one cell, then it will show the address of the first cell in
the range.
#6. Formula Bar
Formula bar is an input bar, below the ribbon. It shows
the content of the active cell and you can also use it enter a formula in a
cell.
#7.
Title Bar
The title bar will show the name of your workbook, followed
by the application name (“Microsoft Excel”).
#8. File
Menu
The file menu is a simple menu as like all other
applications. It contains options like (Save, Save As, Open, New, Print, Excel
Options, Share, etc).
#9.
Quick Access Toolbar
A toolbar to quickly access the options which you
frequently use. You can add your favorite options by adding new options to
quick access toolbar.
#10.
Ribbon Tab
Starting from the Microsoft Excel 2007, all the options
menus are replaced with the ribbons. Ribbon tabs are the bunch of specific
option group which further contains option.
#11. Worksheet Tab
This tab shows the all the worksheets which are present
in the workbook. By default you will see, three worksheets in your new workbook
with a name of Sheet1, Sheet2, Sheet3 respectively.
#12. Status Bar
It is a thin bar at the bottom of the Excel window. It
will give you an instant help once you start your working in Excel.
The
basics of Excel formulas
Before providing the basic Excel
formulas list, let's define the key terms just to make sure we are on the same
page. So, what do we call an Excel formula and Excel function?
Formula is an expression that calculates
the value of a cell.
For example, =A2+A2+A3+A4 is
a formula that adds up the values in cells A2 to A4.
Function is a predefined formula already
available in Excel. Functions perform specific calculations in a particular
order based on the specified values, called arguments, or parameters.
For example, instead of specifying
each value to be summed like in the above formula, you can use the SUM function
to add up a range of cells: =SUM(A2:A4)
